Abstract
The present invention replaces non-ferrous metal brass to be used to make bearing holder and manufacture method thereof at bearing industry with a kind of ferrous material AS cast iron, can be used for all solid cages in bearing ten major types.Casting method for centrifugal, cutting moulding, surface oxidising-parkerized manufacturing process are adopted in the casting of AS cast-iron blank.The mechanical property of AS casting iron bearing solid cage of the present invention, tensile strength, specific elongation, wear resistance, hardness all are higher than the copper solid cage, and cost is low, convenient formation, manufacturing efficiency high and strengthened rustless property, long working life.
Description
The present invention replaces non-ferrous metal to be used to make bearing holder and manufacture method thereof at bearing industry with ferrous metal.
At present, the bearing holder multiselect is made with materials such as steel plate, copper, aluminium, nylon both at home and abroad.The solid cage of all kinds bearing that China produces is more with ZHP59-1 casting lead brass material.Because brass material costs an arm and a leg, cost height, source are nervous, the development of bearing industry has been brought very big difficulty.In order to address this problem, the present invention replaces brass to make bearing holder with AS cast iron.The mechanical property of AS casting iron bearing solid cage, wherein tensile strength, specific elongation, wear resistance, hardness all are higher than the copper solid cage, and have the not available amount of consuming oil of copper retainer, have increased the greasy property of retainer.
The objective of the invention is to be the development bearing industry that new metallic material-AS cast iron of seeking out a kind of " function is constant, and cost reduces, and improves to be worth " replaces non-ferrous metal to make bearing holder.This retainer low cost of manufacture also has convenient formation, manufacturing efficiency height, the characteristics of long working life.
The summary of the invention summary:
